A4 mm-diameter electrical wire is insulated by a 3 mm-thick rubberized sheath (k = 0.15 w/m·k), and the wire/sheath interface is characterized by a thermal contact resistance of 4 × 10−4 m2 ·k/w. the convection heat transfer coefficient at the outer me 3371, fall 2019, simmons page 1 of 2 surface of the sheath is 20 w/m2 ·k, and the temperature of the ambient air is 22◦c. if the temperature of the insulation may not exceed 60◦c, what is the maximum allowable electrical power that may be dissipated per unit length of the conductor? what is the critical radius of the insulation?

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
